for the question its
[(x^-3)(y^-1)] + y^-5] / [(x^-4)(y5)], so basically its all over [(x^-4)(y5)].

and for the answer its the second one...sorry for the mixup.

The questions is
[(x^-3)(y^-1)] + y^-5 / [(x^-4)(y5)]

The answer is (xy^4)+(x^4) / y^10

Did you get it NOW ???

(inside the brackets, for numerators, multiply the Numerator of first with Denominator of second, multiply the Numerator of second with Denominator of first), (and for denominator, multiply both the denominators)
